Ingest Preprocessor
Takes source files which is laid out in a flat file structure (depending on the type of the content source files include master files, derivatives, TEI, XML metadata, etc.) and sorts the files into a directory hierarchy expected by the Ingest Processor
So, it turns a flat directory into many item-level directories.
Calls the ingest process which handles the actual creation and modification of the Fedora objects in the repository

Ingest Processor
Each item dropbox corresponds to a conceptual item. For example, for the “Paged Content Model”, an item is a book, for the “Journal Content Model”, it is a journal volume and so on.
The Ingest Processor takes this directory structure and creates the corresponding object hierarchy in the repository
It also creates a METS document that includes similar structural description of the item
